Jerome Gambit: The Madness Continues

So, the latest game I received from Cliff Hardy, who has been specializing in tortured Jerome Gambit games, is a 1-minute (no increment) bullet game on the website lichess.org - against an International Master.

Of course.

In a game where each player had about one second per move to think, things quickly became exciting. 

Notes by Cliff. [A few by me - Rick] Diagrams by me.

Cliff Hardy - IM Pavel Sevostianov

1 0 bullet, Lichess, 2018 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4....Kxf7 5.Nxe5+ 

In another bullet game recently on Lichess, I forgot this was the move to play, got confused and played 5.Ng5+?? here instead but got justifiably destroyed in short order. I'm glad I didn't make that mistake in this rare chance to play the Jerome against an IM, where I was at least hoping to put up a half-decent game and not waste the opportunity.

5...Nxe5 6.Qh5+ Ng6 

[Interesting - is the IM unfamiliar with the various Jerome Gambit refutations, or does he figure that this will be good enough? It turns out that his "second best" moves are still pretty good. - Rick ]

7.Qd5+ Kf8 8.Qxc5+ Qe7 9.Qe3 Nf6 10.Nc3 c6 

10...d5! -+ would have been the best move here, according to Stockfish, as Black should eventually be able to get the pawn back on d5 (if White were to take it), though it may then take Black a few moves of development first before he could get into a position to win it back.

11.f4? 

Which pawn to push? 11.d4 =+ would have been much better, it turns out.

11...d6? =+ 

Pushing the d-pawn further again with 11...d5! -++ would have been more aggressive.

12.O-O Kf7

13.d3?! -+ 

13.f5 Ne5 14.d4 =+ would have been a better and feistier way to play it for White. 

13...Re8 14.f5 Ne5 15.h3 Kg8 16.Bd2 d5 17.Rae1 dxe4?

Surprisingly, quite an error - 17...Qd6 -+ would have been a better move. 

18.dxe4??

18.Nxe4! +- would have been stronger, when White's threat of Nxf6+ and then attacking the pinned knight on e5 with d4 or Bc3 would have been surprisingly difficult to diffuse e.g. 18...Bd7 19.Nxf6+ Qxf6 (19...gxf6 20. d4 ++-) 20.Bc3 +-.

18...Nc4 19.Qd3 Nxd2 -++ 

19...Nxb2 -++ would also have been good.

20.Qxd2 Bd7 

21.Qf4 Qc5+ 22.Kh1 Qe5 23.Qf3 Re7 -++ 

OK, I'm getting crushed like a bug - but I've still got my Jerome pawns... [And then, there's that clock thingy - Rick]

24.g4 Rae8?? 25.Re2?? 

All right, not the best move - 25.g5! += and the black knight would have been trapped. 

25...h6 26.h4 Nh7 27.Qg2 b6 28.g5 hxg5 29.hxg5 Bc8?

Black appears to be struggling for ideas, despite his material advantage - 29...g6! -++ (intending 30.fxg6 Nxg5) was a brilliant defence to White's pawn onslaught that the computer found. 

30.f6 Rc7 31.f7+

OK, now I'm back in the game, though Stockfish found another surprising resource here in 31.Rf5!?, since 31...Bxf5?? (31...Qd4 32.f7+ = would have been similar to the game) would walk into trouble on the e-file after 32.exf5 +-. 

31...Rxf7 32.Rxf7 Kxf7 33.g6+ Kg8 34. gxh7+ Kh8! 

Black can probably take the h-pawn any time he wants and, by playing this way, keeps more options open by not allowing White to play the queen swap with 34...Kxh7 35.Qh2+.

35.Qh2 Bg4? 

...Though he allows the queen swap now anyway... - keeping the queens on with 35...Qg5 -+ would have been more attacking.

36.Rg2?? 

The last straw for White - 36.Qxe5 Rxe5 37.Re3 would have been about equal.

[White still can win if he stays alive - regardless of the material disadvantage - long enough for Black's flag to fall. He almost makes it. - Rick]

36...Bf3 37.Kg1 Bxg2 38.Qxg2 Re6 39.Kf2 Rf6+ 40.Ke2 Rh6 41.a3 Rh2 42.Kf3 Rxg2 43.Kxg2 Qg5+ 44.Kf3 Qf6+ 45.Ke2 Qg6 46.Ke3 Qh5 47.Ne2 Kxh7 48.Nf4 Qh6 49.Kf3 Qh4 50.Ke3 Qg5 

Not that it matters, but better would have been 50...Qg3+! 

51.c3 Qf6 52.Kf3 Qe5 53.Ke3 g5 54.Nh3 Qh2 

Again, better would have been 54...Qg3+! 

55.Nf2 Qg3+ 56.Ke2 g4 and Black won on time. 

(White had 1.6 seconds left on his clock when Black lost on time).

Jerome Gambit: Odd Turns (Part 2)

[continued from previous post]

perrypawnpusher - Sarantes

"Let's Play The Italian Game" tournament

25.d4 Kf7 26.d5 Bd7 27.e5 dxe5 

Often pawn exchanges such as these are played automatically, but there is an argument to be made for 27...Bf5, instead. Either way, a white pawn is going to advance to e6.

28.fxe5 Ke7 29.e6 Bb5 

Not as bad as it looks, but it doesn't look good.

It takes a little patience, but Black had 29...Bc8 30.Re5 (to protect the d-pawn and forestall the entrance of Black's h-rook) b5 31.c4 bxc4 32.bxc4 Kd6 33.Rg5 Re7 34.a4 b6 35.a5 bxa5 36.Ra1 Ba6 37.Rg4 Ra8 38.Rxa5 Bb7 39.Rxa8 Bxa8 40.Rxh4 c6 and the Bishop will be liberated.

analysis diagram



30.c4 Ba6 31.a4 

Locking up the Bishop while I can. It can still break out with 31...c6, but my opponent's next move is either a mouse slip (shouldn't happen when the time control is a day per move, but, even then, it does) or a slip in assessment - taking a pawn e.p. is not forced.

31...c5 

Now the game definitely swings over into White's favor, as the Bishop is out of play. Capturing the c-pawn would have been a blunder.

My plan is to move the Rooks to the f-file, threaten to enter at f7, and therefore exchange them off. White's King will then easily capture the Kingside pawns as Black dare not leave the control of the "Jerome pawns".

32.Rf1 Ref8 33.Ref3 Rxf3 34. Rxf3 Rf8 35.Rxf8 Kxf8 

36.Kf2 Kf7 37.Kf3 g5 Black resigned

The Bishop is trapped. Black's Kingside pawns will fall. One or more White pawn will Queen.

Jerome Gambit: Odd Turns (Part 1)

I just finished a Jerome Gambit game in an Italian Game tournament at Chess.com. It took a couple of odd turns - played as well as unplayed.

Then, again, that's the Jerome Gambit for you.

perrypawnpusher - Sarantes

"Let's Play The Italian Game" tournament
Chess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 

Jerome's Defense, appearing in his analysis of "Jerome's Double Opening" in the July 1874 issue of the Dubuque Chess Journal, and seen, initially, in Jaeger - Jerome, correspondence, 1880 (1-0, 40).

7.Qxe5 d6 8.Qg3 Nf6 9.d3 Be6 10.O-O Nh5 

Black has a number of choices, as can be seen from some earlier games:

10...Qd7 11.Be3 Bb6 12.Nd2 Ng4 13.Bxb6 axb6 14.h3 Nf6 15.a3 h6 16.f4 Rg8 17.f5 Bf7 18.Qe3 Re8 19.g4 Nd5 20.Qd4 c5 21.Qf2 Nf6 22.b3 b5 23.Qf4 Qc7 24.a4 bxa4 25.Rxa4 b5 26.Ra6 Rd8 27.Rfa1 Ke7 28.Ra7 Black resigned, mrjoker - PhlebasP, Internet Chess Club, 2009;

10...Kf7 11.Be3 Bb6 12.Nc3 Rf8 13.f4 Kg8 14.f5 Bxe3+ 15.Qxe3 Bd7 16.h3 a6 17.g4 c6 18.Rae1 b5 19.Kg2 b4 20.Ne2 a5 21.Qf4 Bc8 22.Ng3 Bb7 23.g5 Ne8 24.d4 c5 25.d5 Nc7 26.h4 Ba6 27.Rf2 Nb5 28.Ne2 a4 29.c4 bxc3 30.bxc3 Na3 31.Qc1 Bxe2 32.Rfxe2 Nc4 33.Qf4 Ne5 34.Rb1 Rb8 35.Reb2 Rxb2+ 36.Rxb2 White resigned, MrJoker - rgiblon, Internet Chess Club 2012; 

11.Qf3+ Nf6 

The placement of White's Queen is problematic. On g3 it is vulnerable to attention by Black's Knight. On f3 it can be harassed by Black's Bishop. It tends to keep Black's King on f8, but that is not, necessarily, a bad thing.

12.Be3 Bb6

Another issue in this kind of position: to exchange Bishops or not. It's probably safe to comment on any exchange with "shouldn't have" and on any non-exchange with "should have exchanged".

13.Nc3 

The Knight has a good "present" here, but I wonder if it would have a better "future" at d2.

13...Kg8 14.Qe2 Qd7 15.f4 Bf7 16.Rae1 Re8 

Black has the extra piece (vs 2 pawns) and the two Bishops. He is not even worried about his Rook at h8. 

White has developed his pieces, and has to find a way to use his "Jerome pawns".

17.Qf3 

I have played over many Jerome Gambits by those much stronger than myself. Sometimes patience is the key. 

17...Qg4 18.Qf2 h5 19.Bxb6 axb6 20.b3 

I admit that this is an odd-looking move. I wanted to be able to play d4 without being bothered by ...Bc4. It just didn't seem to be the time for 21.e5 yet.

20...h4 21.Qf3

I did not like Black's developing action along the h-file, and reluctantly agreed that it was time to swap the Queens.

21...Qxf3 22.Rxf3 Nd5 23.Nxd5 Bxd5 24.Rfe3 Bc6 

Looking at the position, it is clear that White will play d4, and maybe even c4 and g4. He is going to need some help, however.

Black has a solid, attacking Bishop on c6, and both Rooks are in good position. Clearly, he is better.

Jerome Gambit: Artificial Piffle

Okay, I admit it, I was bored. I certainly was not up for a complex, multi-layered intellectual exercise. So, seeing a chessplaying program on my computer, I thought I would while away some time with it - and the Jerome Gambit.

It turns out that I did this once before, 7 years ago - see "Contempt?!" The game does not seem to be in The Database, however. Odd.

I think Microsoft created the Chess Titans program to introduce people to chess. In a world where the world champion would have little chance of defeating top silicon challengers, it turns out that my opponent the other day was not so strong. 

perrypawnpusher - Chess Titans
casual game, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+
Kd6 8.f4 

I was pretty sure that my opponent was not seriously booked up on the Jerome Gambit, and that the killer move 8...Qh4+!? was not going to show up now.

For the record, 8.Nc3 was played by my son against the program years ago, in jon - Chess Titans, 2011 (1-0, 14). That game does not appear in The Database, either. (I will remedy.)

8...g6

I suppose that this was part of the computer's programming, to keep it "weak" - occasionally producing stunners like this.

9.Qxe5+ Kc6 10.Qxh8 

Taking the Rook is best. I got a great game soon after 10.Qd5+, however, frittering it all away and barely surviving to draw in perrypawnpusher - spontex, 8 8 blitz, FICS, 2009 (1/2-1/2, 59). 

10...Qf8 

I also faced 10...d6, leading to an interesting battle, in perrypawnpusher - vermifugo, blitz, FICS, 2014 (1-0, 38)

11.d4 Bxd4 12.Qxd4 h6 

Okay, if it can be said that there was any kind of thread running through this game, it is clear that by now, CT has lost it.

13.Qd5+ Kb6 14.Be3+ c5 15.b4 Qxf4 

I suppose if Chess Titans were my client, I would diagnose clinical depression. Still, there was nothing for Black to be excited about in the computer-recommended 15...Kc7 16.Nc3 Qg7 17.Qxc5+ Kd8 18.Bd4 Qe7 19.Qa5+ Ke8 20.O-O-O. 

16.Qxc5+ Ka6 17.Qa5 checkmate

BSJG: Another Riot of A 3-Minute Battle

Here is another quick game from chessfriend shugart, showing his interest in: attack, attack, attack! The fast time control is his friend.

I have added a few analytical notes, but not too many - I hope - because I don't want to dilute the fun of playing over another King hunt.

shugart - Tseatsy
3 0 blitz, 2018

1.e4 e5 2. Nf3 Nc6 3. Bc4 Nd4

4.Bxf7+ 

The Blakckburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 6.Qh5 

The Database has 125 games with this move. White scores 57%. That compares well with the recommended 6.c3 (449 games, 60%), which shows the effect, at least in part, of the quick time control.

6...Nf6 7.Qf7+ Kd6 

Black is suspicious of the second piece sacrifice. In his next game (the one we saw first, in the previous post) he went for the capture with 7...Kxe5.

8.Nc4+ 

Going after the King. White is making his way through a messy line where the alternative ("best") play involves mutual King forks followed by wins of Rooks: 8.c3 Nc2+ 9.Kd1 Nxa1 10.d4 Qe8 11.Qxe8 Nxe8 12.Nf7+ Ke6 13.Nxh8 with advantage to Black. 

8...Kc5 9.b4+ Kxb4 

Taking the pawn is too risky, but in a 3-minute game it is sometimes recommended that you grab the material, and see how it all works out...

10.Ba3+

This certainly looks strong, and it turns out fine, but the fork 10.c3+ was probably the way to go.

10...Kb5 11.Nc3+ Ka6 12.O-O 

It looks like Black's King is doomed, but he has the wonderful 12...Ne6!? to cut off White's Queen and save the day. However, in a blitz game that is a resource that can be difficult to find. Black swaps off some pieces - and falls into a mating trap.

12...Nxc2 13.e5 Nxa3 14.Nxa3 Bxa3 15.Qc4+ Black resigned

Checkmate is coming.

BSJG: A Riot of A 3-Minute Battle

I recently received a couple of games from shugart, who plays online at the Free Internet Chess Server (FICS). He has about 150 games in The Database, and they tend to be like the following, "a riot of a 3-minute battle" (see "Blackburne Shilling Jerome Gambit: Risk vs Experience").

Please do not hurry to run to the nearest computer engine, just relax and enjoy the full-out conflict.

shugart - Tseatsy

3 0 blitz, FICS, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4

The Blackburne Shilling Gambit. A tricky opening that probably works best in fast time control games like this one.

4.Bxf7+ 

The Blackburne Shilling Jerome Gambit.

According to The Database, Tseatsy has encountered this move at least 28 times, scoring 61%. A fine opponent for shugart!

4...Kxf7 5.Nxe5+ Ke6 6.Qh5 

Like White's 4th, this is a signature move of the Jerome Gambit and its relatives. At a slower time control, 6.c3 might be the move of choice, but here White is commanding: Think fast!

Checking The Database, I note that Tseatsy had not faced this move before this day.

6...Nf6 7.Qf7+ 

More sacrifice. At some point Black's King will catch his breath and count up his riches - if White gives him a chance.  

7...Kxe5 8.f4+ Kxf4 9.O-O+ Ke5 

Black is ahead a couple of pieces, but, oh, that King!

10.d3 Ne2+ 11.Kh1 Nxc1 12.Rf5+ 

White is not going to win the match on points, he is going for the knockout.

12...Kd6 13.e5+ Kc6 14.Qc4+ Bc5 15.Nc3 d6 16.Qb5 checkmate

Very nice!

(By the way, this was the second time that day that Tseatsy faced the Blackburne Shilling Jerome Gambit at the hands of shugart. This game lasted a move longer than the earlier one - as we shall see next post.)

Jerome Gambit: In the Meantime

White waiting for the second round to begin in the "Italian Battleground" tournament at Chess.com, (1 game to go now in Group 3, although it will determine the final player to advance to the second round), I decided to join the "Let's Play The Italian Game" tournament on that site, as well: 15 players, split into 5 groups of 3, the winner of each trio advances. I have played 3 games so far - one of them a Jerome Gambit (yay!). (I won a game with Black, and another game with White that I was unable to transform a Two Knights into an Italian Four Knights Jerome Gambit.) 

I also wandered over online to FICS, and was able to snag a blitz game - against an opponent who was probably having a bad day. Still, the game had a bright moment for me - because I remembered the recent post here, "Jerome Gambit Secrets #5"!

perrypawnpusher - juliebabe
6 12 blitz, FICS, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Ne7

Black hits back against the White Queen - in this situation, it is not enough.

In "Jerome Gambit Secrets #5" I noted

When I posted the game on this blog, back then, I recommended, instead [of 8...Ne7], 8...Qh4!?, which  had been played a number of times before - as early as a supposed 1899 telephone game - and which continued to be played, year after year. (So: 8...Qh4 isn't much of a "secret".)

The odd thing is, when I was reviewing the current game I had Stockfish 9 do a "blunder check", and it recommended that Black's King simply walk away with 8...Kc6!?, allowing 9.Qxe5, but giving Black a won game. The Database has 3 games with this suggestion, all wins for Black. (I can't decide if keeping the 8...Kc6 secret from the "Secret" was intentional or sloppiness.)

9.Qxe5+ Kc6 10.Qc3

It would be hard to forget this move after playing over Hardy, C. - NN, 10 0 blindfold, lichess.org, 2018 (1-0, 13) - " 10.Qc3!, intending 11.b4 or 11.d4, with a strong attack".

10...d6

Nine years ago I played a game that continued 10...Qf8 11.d4 Qf6 12.Qxc5 checkmate, perrypawnpusher - nicolasalk, blitz, FICS, 2009, but it had slipped my mind. 

11.d4 Kd7 12.dxc5 dxc5 13.O-O b6

The distractions of the Jerome Gambit are too much. It does not help that the computer considers as best even more King wandering, i.e. 13...Kc6 14. Qf3 Kb6 although Black would still be lost.

14.Rd1+ Ke8 15.Rxd8+ Kxd8 Black resigned
